Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed September 13,1906. Serial No. 334,398.

To all whom it may concern:

Be it known that I, CONRAD BAUER, of Pittsbwg, in

the county of Allegheny, State of Pennsylvania, have invented a certainnew and useful Improvement in Screens, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which Figure 1 is avertical sectional view of a window provided with my improved screens;Fig. 2 is an enlarged vertical sectional view illustrating the operatingmechanism; Fig. 3 is a perspective view illustrating theshutter-screen-guide and latch; Fig. 4 is a perspective viewillustrating the connection between the shutter-slats; Fig. 5 is a fiontelevation partially in section and partially broken away illustrating myinvention; Fig. 6 is a vertical sectional view illustrating the shutterextension arms..

Like symbols of reference indicate like parts wherever they occur.

My invention relates to an improvement in screens and I have shown it asapplied to a shutter-screen in combination with a fly-screen for awindow, although it may be used in a like manner in connection withother kinds of blinds, and for doors and awnings.

In the drawings 2 represents the shutter-screen, and 3 is thefly-screen, the shutter being adapted to roll on a roller 4 at the topof the window-frame, and the fiyscreen being adapted to roll in rear ofthe shutter on a roller 5, the roller 5 being mounted a short distancebelow the roller 4, and both the roller 4 and the roller 5 are journaledat one end in the vertically sliding bar 6,

the journals of the rolls, passing through slots in the stationary barof the frame 7. Keyed to the journal of the roller 4 is a gear-wheel 8and keyed to the journal of the roller 5 is a gear-wheel 9. Midwaybetween the gear-wheels 8 and 9 is a gear-wheel 10 which is fixed to asprocket-wheel 11 and is journaled in the stationary bar 7. Thevertically sliding bar 6 is operated by.

means of the lever-arm 12 which is pivoted to a stationary bracket 13and is connected with the slidingbar 6 by-a slot and pin as is indicatedat 14 in Figs. 1 and 2. Extending from the outer end of the leverarm 12is the rod 15 which is provided witha handle 16 by means of which therod 15 and lever 12 may be operated to move the bar 6 and to throw thegear- .wheels 8 and 9 alternately into gear with the gearwheel 10according as it may be desired to roll or unroll the fly-screen or theshutter. Above the gear-wheel 8 is a pin 17 and below the gear-wheel 9is a similar'pin 18. When the bar 6 is raised and the gear 8 is therebythrown out of connection with the gear 10, the pin 17 comes between thecogs of the gear-wheel 8 and locks .the same. By the same movement thecogs of the gear-- wheel 9 are released from the pin 18, unlocking thegear-wheel and bringing it into mesh with the gearwheel 10. .Thesprocket-wheel 11 is operated by the sprocket-chain 19, which, engagingwith the teeth of the sprocket-wheel, passes over the guide-rollers 20at the top of the window-frame and guide-rollers 21 at the bottom of thewindow-frame. By pulling on the sprocket-chain 19 in one direction thefly-screen or the shutter, according to the connection of thesprocketwheel 10, will be raised or lowered, and, by pulling on thesprocket-chain 19 in the opposite direction, a reverse action will takeplace.

The fly-screen may be formed of any suitable material such aswire-netting, and it may be provided with suitable stiffening battens22, which battens extend' transversely and fit in the guides 23 securedat the sides of the window-frame.

The shutter 2 is formed of transverse slats, preferably I window-framedownward to-a point about one-third of the distance from the top to thebottom, and in swinging guides 28, which extend from the bottom of theguides 27, to which they are hinged by hinges 29, to the bottom of thewindow-frame. At the bottom of the window-frame the free ends of theswinging guides 28 are connected with each other by the transverse rod30. On each side of the window-frame, pivoted to the rod 30 arelever-arms 31, the outer end of which arms are pivoted to the verticallymovable slides 32, which are adapted to slide on the vertical standards34 and to be locked thereon at any desired position by the set screw 33.By lowering the slides 32 on the standards 34, the lever-arms 31 will bebrought from a vertical to a horizontal position, thus extending thelower ends of the swinging guides 28 away from the window-frame,theguides moving on their hinges 29, and thus forms an awning. When theshutter is lowered audit is desired to lock the same, the spring-lock 35engages with the lug 36 on the window-sill. The thimbles 26 shown indetail in Fig. 4 secured by the connecting links, keep the slats at anequal desired distance apart and also serve as a protection to the slatsthemselves, preventing them from being injured during the rollingoperation.

The operation of my improved shutter will be readily understood from theforegoing description.

Many variations in the form and structure of the different parts may bemade by those skilled in the art, without departing from the spirit ofmy invention.

The advantages of my invention will be appreciated by those skilled inthe art. The blind is not only strong, rigid and durable, but it is alsosimple and easy of operation.

Having thus described my invention, what I claim and desire to secure byLetters Patent is: 1. In a window-screen, the combination of a roller,:1

screen adapted to be wound on the roller, means for actuating theroller, means for disengaging said roller from the actuating means andbringing it into engagement with locking means, hinged guides at thesides of the screen within which the screen is adapted to move, anddevices for extending and securing the guides and'screen outwardly tovarying distances from the window-frame.

2. In a window-screen, the combination of a roller, a screen adapted tobe wound thereon, a roller and an inner screen adapted to be woundthereon, drive-wheels secured to the ends of the said rollers, anintermediate drivewheei, devices for bringing either of the rollerdrive-wheels into connection with the intermediate drive-wheel andthrowing the other of the roller drive wheels out of conncction with theintermediate drive-wheel, and mechanism for imparting power to theintermediate drive-wheel.

3. In a window-screen, the combination of a roller, a slatted screenadapted to wind on the roller, actuating mechanism and a locking deviceadapted to be alternately connected to the roller, fixed guides in whichthe edges of the slatted screen are adapted to move, movable guideshinged to the fixed guides, rigid extension arms one end of each ofwhich is pivoted to the lower end of the swinging guides, and verticallymovable slides to which the other ends of the extension arms arepivoted.

4. In a window-screen, the combination of an outer screen an innerscreen, a roller adapted to wind the outer screen, a roller adapted towind the inner screen, a vertically movable housing within which the tworollers are journaled, gear-wheels on the ends of the rollers, anintermediate gear-wheel journaled in fixed housings, de-

vices for throwing the roller gears in and out of mesh with theintermediate gear, a sprocket-wheel fixed to the intermediate gear, anda sprocket-chain meshing with the sprocketwheel.

5. In a window-screen, the combination of a roller, a screen adapted tobe wound on the roller, means for actuating the roller, means forsimultaneously locking the roller and disengaging the actuating meansand for simultaneously unlocking the roller and connecting the actuatingmeans thereto, hinged guides at the side of the screen within which thescreen is adapted to move, and devices for extending the guides from thewindow-frame and for locking the same in position.

6. in a window-screen, the combination with a windowframe, of inner andouter screens, rollers upon which said screens are adapted to be wound,actuating means there- I 8. In a window-screen, the combination with awindowframe, of inner and outer screens, rollers upon which said screensare adapted to be wound, an actuating device therefor, locking devices,and means for simultaneously engaging said rollers with or disengagingthem from said actuating device and said locking devices, whereby eitherroller may'be actuated.

9. In a window-screen, the combination of slats, thimbles fitting on theslats and provided with openings adjacent the top and bottom thereof,and a connecting device for said slats passing through the openings insaid thimbles and between the thimbles and slats, whereby the adjacentconnected edges of the slats are held in parallel relation in theprocess of operation.

10. In a window-screen, the combination of slats, thimbles fitting onthe slats and provided with slots adjacent the top and bottom of theslats, and a connecting device for said slats passing through said slotsand between the thimbles and slats, whereby the adjacent connected edgesof the slats are held in parallel relation. v
